Holy cow!

There's a used bookstore in Baltimore called Book Thing that gives away all its books.

From their FAQ:

Are the books really free?: Yup.
Really?: Yes.
Absolutely free?: Yes.
What's the catch?: All the books have been stamped "not for resale" and are not to be resold. It means what it says. Please honor this request.

Is there a limit to how many books I can take?: You can only take 150,000 per day, per person.

How badly to I want to go to Baltimore right now???
